Potassium Carbonate → (2R)-2-methyl-2-(methylsulfonyl)-4-{2-oxo-4-[4-(1H-pyrazol-1-yl)phenyl]pyridin-1(2H)-yl}-N-(tetrahydro-2H-pyran-2-yloxy)butanamide

Reaction Steps

Trisdibenzylidine dipalladium (29 mg, 0.049 mmol) was added to a mixture of potassium carbonate (343 mg, 2.46 mmol), 1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1H-pyrazole (133 mg, 0.49 mmol) and (2R)-4-(4-iodo-2-oxopyridin-1(2H)-yl)-2-methyl-2-(methylsulfonyl)-N-(tetrahydro-2H-pyran-2-yloxy)butanamide (245 mg, 0.49 mmol), which may be synthesized as described in Preparation 2B in 1,2-dimethoxyethane-methanol (5.0 mL, 1:1). The reaction was heated to 80° C. and allowed to stir overnight. The reaction was diluted with ethyl acetate (10 mL), filtered through a pad of Celite, and concentrated under reduced pressure. The crude material was purified by flash chromatography (1:0-9:1 ethyl acetate/methanol) to provide a colorless residue (58 mg, 23%). MS (LCMS) m/z 513.7 (M−1).
